Nanostructure of Zinc(II) tetraphenylporphyrinate langmuir M-monolayers formed with diluted solution

Abstract

Using quantitative analysis of isotherms the main characteristics of the structure of zinc tetraphenylporphyrinate (ZnTPP) floating M-monolayers formed with diluted solution have been determined. These include the size of M-nanoaggregates and the number of molecules in them, the distance between aggregates, the content of bound water and water between aggregates, the compressibility, and the pressure and current surface concentration ranges corresponding to stable states. The dependencies of main characteristics from the initial surface coverage found allow one to estimate the highest aggregation number.
